Unable to run gtk-demo for gtk+-2.14.6 with DirectFB : help!!!!!!!!!!!!!!!

["Dhananjoy Chutia" <dhanrd@xxxxxxxxx>]

Hi,
   gtk+-2.14.6 compilation was failed for arm-linux with
directfb. I had compiled gtk+-2.14.6 with configure option
--with-gdktarget=directfb --without-x --disable-gdiplus
--without-libtiff --disable-gtk-doc --disable-man --disable-glibtest
--without-libjasper. It is to be noted that glib version is
glib-2.18.3, directfb version is 1.2.0.

Then, I applied the patch available in the link:

http://bugzilla.gnome.org/attachment.cgi?id=122159&action="">

The compilation broke even after that, so the following change as per the patch was reverted back in the file: gtk+-2.14.6/gdk/directfb/

gdkwindow-directfb.c directfb/gdkwindow-directfb.c

  while (tmp_list)
    {
      GdkWindowObject       *private = GDK_WINDOW_OBJECT( tmp_list->data );
-      GdkWindowImplDirectFB *wimpl   = GDK_WINDOW_IMPL_DIRECTFB( private->impl );

      if (private->update_freeze_count)
        {

Ultimately, compiled well.

But, when I run gtk-demo provided with the package, in the target device the application crashes, showing Segmentation fault.

Here is the back trace...........

As, per my observation, the application is unable to initialize the window....
Can anyone help me to work with gtk with directfb backend.........?
